3. Precautions for Use
The following precautions must be taken when using the instrument.
● Sampling
There are possibilities of particle deposit/rescattering when sampling is performed by using a
tube connected to the inlet. It is recommended that sampling is performed without using the tube.
However, if a tube is required for sampling, the tube recommend below must be used.
● Sampling Tube
Recommended Sampling Tube:
TYGON Inner Diameter 4.3mm × Outer Diameter 7.5mm: Product or Norton
This product can be purchased from dealers of physical and chemical equipment, as well as
through our sales offices.
● Power
The instrument can be powered by AA batteries or AC power.
● AC Power
For AC-powered operation, the dedicated AC adapter supplied with the instrument must be used.
The AC adapter accommodates voltage of AC 86-264V 50/60Hz, however, the connection plug is
dedicated to AC 100V.
● AA Batteries
In addition to the supplied AA rechargeable batteries (Ni-MH 1.2V 1600mA), alkali batteries can
be used as well.
Maximum continuous operating hours:
- When using alkali batteries : 1 hour
- When using the supplied rechargeable batteries : 3 hours
The above continuous operating hours are subject to change due to operational conditions such as
ambient condition, or use of the sampling tube.
● Caution for Extremely Long Measurement Periods
The instrument is unsuitable for continuous measurements for a prolonged period. It may hasten
deterioration of the light source and inner pump, and require maintenance in a shorter interval.
● For Prolonged Measurements
Note that the data will not be saved if the power is cut during a measurement.
Make sure to prevent running out of batteries or power cut of AC power.
● Sampling Environment
The instrument is designed for use in clean rooms or clean environments where the concentration
is below the maximum measurable concentration of 2,000,000 particles/cf. Using the instrument
in a high temperature/humidity environment or in an environment with high particle
concentration may cause damage to the instrument or shorten the maintenance interval.
